U Mobile's Information Systems Division, working with AWS and AWS Partner Axrail, built AiDaH, an AI-Driven Agentic Helpdesk on Amazon Bedrock AgentCore, which now handles over 150 documented operational scenarios across six business divisions. According to U Mobile's internal measurements, monthly trouble ticket volumes fell by up to 84.5 percent in provisioning and network tickets, 81.6 percent in general inquiries, and 48.7 percent in billing and charging between January and September 2026.
